Scheduled Maintenance
As advised by Cisco TAC, EX Networks will be performing a software upgrade on the core router located in Telehouse North – zephyr.thn.exn.uk. We will be upgrading the version of IOS-XR which will introduce several bug fixes to ensure service stability as well as a number of new features.

Due to the nature of this upgrade, the router and line cards will need to be reloaded. This will cause an outage for directly connected clients, and BGP sessions both with clients and upstream Tier-1 partners as well as peering exchanges.

At EXN we designed our network with maintenance and outages in mind, and as such upstream connections and linknets between data centres will be gracefully failed over before the reload. This means only directly connected clients and client BGP sessions will be “DOWN” during the reload. Other services should be considered “AT RISK” during this work.

As these routers have several line cards and FPGA’s there will be several reloads of individual components. Therefore, all client facing ports will be shutdown and EXN engineers will confirm the stability of the device before bringing the ports back up.

Over the next few days the affected clients will be contacted individually by EXN.
